If you retract too quickly, the filament may separate from the hot plastic inside the nozzle, or the quick movement of the drive gear may even grind away pieces of your filament. There is usually a sweet spot somewhere between 1200-6000 mm/min (20-100 mm/s) where retraction performs best.
What is a good PLA retraction speed?
Materials like ABS and PLA will do well with a speed of 40 to 60 mm/s and a retraction distance of 0.5 to 1.0 mm on direct drive extruders.
What happens if retraction speed is too high?
When the retraction speed is too high, some parts of the printed object don’t get enough filament. Or, even worse, the nozzle gets jammed. A retraction distance that’s too high would cause blobs or zits in print and might even lead to clogs or jams.
How do I calculate retraction settings?

What is a good retraction distance 3D printing?
A typical retraction distance ranges from 2 to 7 mm, but this value depends on your extruder configuration (direct drive or Bowden), hot end, and other factors; there’s no one perfect value.
What is a good retraction speed for Ender 3?
Retraction Speed – A good value to start with is 20mm/s. You can afterwards always can raise this value through a stringing test (links below).
What are Cura retractions?
Retraction distance changes how far back the filament is pulled. Too low of a value will not properly relieve pressure in the hot end, but too high of a value can cause jams and clogs. Starting with the default Cura settings and tweak the distance by 1 mm at a time to find the optimal value.
Is faster retraction speed better?
Retraction Speed – Retraction speed should not be too low because the filament will begin to ooze from the nozzle before it reaches the exact point. It should not be too fast because the extruder motor will reach the next location quickly and the filament will extrude from the nozzle after a short delay.
